Your Philips Hue Bulbs Just Learned to Speak Two Languages at Once

On October 5, Philips Hue quietly began rolling out the most technically interesting firmware update its lights have ever received. Version 1.164.2, released for lamps on the company's 100b-129 hardware platform, lets compatible bulbs speak Zigbee and Matter over Thread at the same time. Until now, owners of newer Hue bulbs had to pick one protocol at setup: connect through Zigbee to the Hue Bridge, or connect directly over Thread to a Matter controller, with the road not taken sealed off. This update removes that fork in the road, and in doing so it quietly resolves one of the smart home's most annoying trade-offs.

What firmware 1.164.2 actually changes

Philips Hue's published release notes list four items: bug fixes and stability improvements, support for Matter 1.4.1, support for Matter Apple adaptive lighting, and, the headline feature, support for Zigbee and Matter concurrency in bridgeless mode. The update applies to the 100b-129 hardware platform, which covers every new Hue product released in 2026 plus the E27 bulbs and GU10 spotlights from fall 2025. What those lights have in common is a Thread radio, and the underlying hardware comes from Silicon Labs' MG26 and SiMG301 wireless chips.

The capability behind the feature is called concurrent multiprotocol, or CMP, and it has been in the works for months. Back in the summer of 2026, Signify and Silicon Labs announced they would bring CMP support to select Hue bulbs via a software update later in the year. October 5 was when that promise landed. It is worth noting the limits: the rollout covers mains-powered lamps, not the battery-powered sensors and accessories, which lack the radio hardware to pull this off.

Why running both protocols matters

To understand why this matters, it helps to see what the old setup demanded. A Hue bulb bought in the last year or so carried two possible identities. Commission it over Zigbee and it lived on the Hue Bridge, fast, reliable, and fully featured, but walled into Signify's corner of the smart home. Commission it over Matter and Thread instead and it joined any Matter controller, Apple Home, Google Home, Alexa, or SmartThings, without a Bridge. The catch: choosing one disabled the other. Switching between them meant a factory reset and a fresh round of pairing, which is nobody's idea of a fun Saturday.

Concurrency ends the penalty for picking wrong. The second, subtler benefit is about the Thread network itself. Thread is a mesh protocol, which means mains-powered devices relay traffic for one another. Philips Hue bulbs, which draw constant power from the socket, make excellent mesh anchors. A bulb that stays reachable on Thread while also answering to the Hue Bridge strengthens the whole Thread mesh, potentially bringing distant Thread devices, the ones at the edge of coverage, more reliably into reach.

Matter promised one standard for everything. Philips Hue just conceded that the real world will run two of them for a while, and built a bulb that refuses to choose.

The one-way door finally opens both ways

The practical scenario the update unlocks runs in reverse. The Hue-focused outlet Hueblog, reporting on the update October 8, noted that a light first set up over Thread can now be added to a Hue Bridge later without re-pairing. That is a bigger deal than it sounds. People change ecosystems: they buy into a Bridge-based setup after starting bridgeless, they switch from a Google household to an Apple one, they inherit a pile of bulbs from a previous apartment. Every one of those migrations used to begin with a factory reset.

For existing Bridge owners, the honest assessment is more measured. Nearly every Hue product can already be reached through Matter via the Hue Bridge itself, so a simultaneous direct Thread connection adds little in the way of new control options. As Hueblog put it, from a control standpoint there is likely no advantage to having a parallel direct Thread connection for Bridge users. The value lies in the mesh and in migration freedom, not in a second way to turn the light on.

The questions Philips Hue has not answered

There are gaps in the picture, and they are worth flagging. The release notes phrase the feature as concurrency in bridgeless mode, which raises the obvious question: what exactly does concurrency look like once a bulb is paired to a Bridge? The notes do not spell out how the two radios behave in that configuration, and independent coverage has flagged the ambiguity. Early adopters will be mapping those edges in the coming weeks.

There is also the matter of everyone left behind. Only bulbs on the 100b-129 platform get the update, and older Zigbee-only bulbs cannot be upgraded by any amount of firmware, since they lack the Thread radio entirely. Philips Hue's dual-protocol future is, for now, a future for people who bought new hardware in the last twelve months or so. And while Apple adaptive lighting over Matter is a nice touch for the Apple side of the house, it underscores how ecosystem-specific perks still trail behind the universal standard in this transition period.

What this says about the Matter bet

Step back and the strategy is revealing. Signify did not pick a winner between Zigbee and Matter; it decided the winning move was not to pick. That is an admission that the industry's great unification project is a migration, not a switch, and that the smart home of the next several years runs bilingual. It also reflects a quiet hardware reality: the bridge-heavy architectures of the last decade and the Thread meshes of the next one are both going to be in living rooms at the same time, and devices that span both will have a longer useful life than devices committed to one.

There is a broader lesson for anyone building a smart home in 2026. Protocols are infrastructure, and infrastructure upgrades best when the old and new can share the same copper, or in this case, the same bulb. Philips Hue's update is small in the release notes and large in what it implies: the end of lock-in by protocol, one firmware push at a time. For owners of compatible bulbs, the advice is simple. Check the Hue app in the coming days; if the update has landed, your lights just got a second language, and this time you did not have to teach them.
